Unfortunately, The Focal 1038be is a beast of a speaker that will require a lot of power to open up and sound right. Neither of these tube amps are going to provide what these speakers really need, O sure they could drive them to a degree but its pedestrian a real waste of a good speaker. I would put the tubes into a seperate pre amp and get a powerful clean solid state amp like McIntosh, Bryston, Pass labs, ect...
